Circulation of hydraulically ponded turbidity currents and the filling of continental slope minibasins [PDF]
Nature CommunicationsNatural depressions on continental margins termed minibasins trap turbidity currents, a class of sediment-laden seafloor density driven flow. These currents are the primary downslope vectors for clastic sediment, particulate organic carbon, and ...

How Fast Can Minibasins Translate Down a Slope? Observations from 2D Numerical Models
Tektonika, 2023 Minibasins are important features in salt-bearing basins and are abundant in salt-detached continental slopes where the salt and the overlying sedimentary cover (including minibasins) undergo seaward translation due to gravity.

Principles of shortening in salt basins containing isolated minibasins
Basin Research, 2021 Shortening styles in salt-influenced basins can vary markedly, with the volume and distribution of salt prior to shortening being a key control. Here we use a suite of physical models to examine styles of thin-skinned regional shortening in settings where the pre-shortening structure comprised minibasins surrounded by salt (‘isolated-minibasin ...

Inversion of accommodation zones in salt-bearing extensional systems: insights from analog modeling [PDF]
Solid Earth, 2023 This work uses sandbox analog models to analyze the formation and subsequent inversion of a decoupled extensional system comprised of two segmented half-grabens separated by a diffuse accommodation zone with thick early syn-rift salt.

Marine and Petroleum Geology, 2021 Abstract Recent subsurface studies show that mass-transport deposits (MTDs) in salt-controlled basins may correspond to local or regional bodies induced by either regional tectonics, or diapir growth. These MTDs are commonly considered as muddy bodies but they may alternatively incorporate a high amount of clasts and reworked beds with good reservoir

Overprinting translational domains in passive margin salt basins: insights from analogue modelling [PDF]
Solid Earth, 2019 Current models of gravitational tectonics on the structural styles of salt-influenced passive margins typically depict domains of upslope extension and corresponding downslope contraction separated by a mid-slope domain of translation that is rather ...

‘Halo-kinematic’ sequence-stratigraphic analysis of minibasins in the deepwater contractional province of the Liguro-Provençal basin, Western Mediterranean [PDF]
Marine and Petroleum Geology, 2020 This study investigates the co-evolution of gravity-driven thin-skinned salt tectonic processes and minibasin-scale halokinetic-depositional processes for the kinematic analysis of salt diapirs in the diapiric province of the contractional domain of the ...

Unpredictable geometry and depositional stacking patterns of mass-transport complexes in salt minibasins [PDF]
Marine and Petroleum Geology, 2020 Mass-transport complexes in a salt minibasin of the Espírito Santo Basin (SE Brazil) are investigated using a high-quality 3D seismic volume and borehole data. A series of six (6), stacked MTCs were identified from the sea floor down to an approximate depth of 1.5 km. These MTCs exhibit a high variability in size and internal structures.

Salt tectonics in the Sivas basin (Turkey): crossing salt walls and minibasins
Bulletin - Societie Geologique De France, 2014 AbstractThe Sivas basin (Turkey) shows pronounced salt tectonics activity involving the Oligocene evaporites. Despite the complete exposure of the structures, the tectonic evolution of the basin has been so far misunderstood because it has only been envisioned in a context of thrust tectonics.
